FunctionSyntaxin (Stx) are membrane-integrated proteins that are instrumental in exocytosis of vesicles. Stx-1 is essential for the formation of the SNARE complex involved in the fusion machinery in the brain. Stx-1 forms a 4-helical bundle complex with proteins SNAP-25 and VAMP2 which drives fusion of vesicles with the plasma membrane[1]. The coiled-coil bundle structure is formed by the interactions of the complex SNARE motifs[2]. RelevanceThe blockade of Stx-1 inhibits glioblastoma tumor growth and may represent a novel therapeutic tool against this fatal tumor[3]. Structural highlights(PDB code 3hd7). The interactions of the syntaxin 1a and VAMP2 SNARE motives consist of hydrogen bond and polar interactions[4]. (PDB code 3ipd).
